These two cars have very different internals, which isn’t surprising considering one was born on American roads, while the other on the autobahn. For comparison’s sake, here is a breakdown of the two cars.

Cadillac CTS-V

Engine: Supercharged 6.2-liter V8

Horsepower: 640 hp

Torque: 630 lb-ft

0-60 mph: 3.7 seconds

Porsche 911 GT3 RS

Engine: 4.0-liter Flat 6

Horsepower: 500 hp

Torque: 339 lb-ft

0-60 mph: 3.1 seconds

From those specs, you can see that the 0-60 times between the two cars are very different. Is the 911’s 0.6 second lead in the 0-60 time enough to rocket it ahead of the CTS-V? Well, just click play below and it will become very apparent.
